Summary

The text uses a unique spiral organization that introduces functions, graphing and trigonometry early in Part I, then revisits these topics with a more sophisticated approach after further algebraic techniques have been developed. This early introduction helps instructors inject new and central topics at the beginning of the course and helps provide a more integrated treatment of algebra and trigonometry that can take advantage of modern technology. Trigonometric expressions are carried along simultaneously with the work in algebra so that students can see that algebraic and trigonometric expressions are handled in basically the same way.
Part II uses an "elementary functions" approach, with the function concept playing the unifying role in the study of linear, quadratic, polynomial, rational, exponential, logarithmic, and circular functions. The text concludes with traditional chapters on analytic geometry, systems of equations, and discrete algebra.

Features


Provides a spiral approach that introduces topics on a basic level and then revisits them in later chapters for further development.
"Technology Links" provide discussions on using graphing calculators and are integrated throughout the text.
Each section opens with a motivational problem that is solved later as an example problem.
"Explore" exercises promote discovery and cooperative learning.
"Thinking About It" exercises help develop critical thinking skills.
Application problems are included in the examples and exercises of every section.
Specific objectives are listed at the beginning of each section.
Each chapter summary begins with a checklist of objectives that is illustrated by Example Problems.
Each Example Problem has an associated "Progress Check" exercise.
Effective use of color enhances the many images in concept developments and exercise sets.
